Verify the result given by Eqs. (f) and (g) of Section 3.12 (a) by rewriting Eqs. (d) and (e) in the following forms, respectively,

and by integrating (P3.35); (b) by expanding Eqs. (d) and (e), setting t=1n r, and thereby transforming the resulting expressions into two ordinary differential equations with constant coefficients.
